Basic principles for network management

1.1 How to use the Wizard function

Wizard is a new function which provides an easier and faster way for

users to set up switches. The wizard includes four often-used basic

settings, which are:

Basic

Protection

VLAN

QoS

Wizard interface

10/215

www.zyxel.com

Note:

1. Applying configurations made in the Wizard menu will cause all other

configurations not supported in the Wizard to return to default settings.

2. Original VLAN configurations set on Web GUI will NOT be merged into the

Wizard.

Following example was tested using XGS1930-28HP (Firmware Version: V4.50).

This feature is for L2 capable switches only.(Only for XGS1930 series)
